Abstract

UN PROCEDE POUR LA PURIFICATION D'UN MONOMENE VINYLAROMATIQUE CONTENANT UN INHIBITEUR DE POLYMERISATION PHENOLIQUE, EN LE FAISANT PASSER PAR DESSUS UN LIT FIXE DE PARTICULES D'ALUMINE, CARACTERISE PAR LE FAIT QUE LA DIMENSION GRANULOMETRIQUE DES PARTICULES VARIE ENTRE 0,5 ET 3 MM, LA VITESSE SPATIALE DU MONOMERE SE SITUE ENTRE 0,5 A 7,5 H-1 ET LA VITESSE LINEAIRE DU MONOMERE ENTRE 0,125 A 45 M/HA PROCESS FOR THE PURIFICATION OF A VINYLAROMATIC MONOMEN CONTAINING A PHENOLIC POLYMERIZATION INHIBITOR, BY PASSING IT THROUGH A FIXED BED OF ALUMINA PARTICLES, CHARACTERIZED BY THE FACT THAT THE GRANULOMETRIC DIMENSION OF THREE AND THREE MM PARTICLES , THE SPACE SPEED OF THE MONOMER IS BETWEEN 0.5 TO 7.5 H-1 AND THE LINEAR SPEED OF THE MONOMER BETWEEN 0.125 TO 45 MPH
